Defender Puma. Lubricating diff lock linkages

[MikeXX]

Hope this is the correct board.

My vehicle is a Defender 110 Puma Hard Top County with fully carpeted cab. The linkages that operate the diff lock seem to be siezed and need freeing/lubricating. I am just hoping someone can give me a step by step guide how to do this. Do I need to remove the carpets & gain access from above or struggle underneath the vehicle?

Thanks

werd that it has,

its easy enoght to get at it from underneath, taking the tunel cover off i a mission to get back on and slightly sealed

Here is a pic of the linkage on our Puma. Removing the drivers floor is very difficult and I gave up removing the tunnel as I couldn't get the air cond unit out.

Best serviced from underneath if you can

Thanks Bundalene & stig0000,

A picture tells a thousand words.

I will endeavour to sort it from underneath initially. Although I am not sure access is so straightforward. I guess it depends on the facilities you have available. I do not have indoor/workshop facilities & we have 18 inches of snow outside & still snowing!

I have an electric spray gun and thought I might try spraying Kerosine over the offending linkages initially just to see if I can get them moving.

I am a bit ****ed off because this happened to my last Land Rover & I specifically asked the service mechanic to lubricate these linkages when the vehicle was serviced. I also blame Land Rover for not addressing what seems to be a recurring problem. I also blame myself for not keeping my eye on this problem as I have had similar problems before.

My vehicle does not have air conditioning so would it be so difficult to access the problem from above?

Bundalene,

Looking at the photo can you advise me if the lever is in the diff lock engaged position?

Please also which way engages/disengages the diff lock?

Thanks

Hi, just a thought;

to get better access to this it may be easier to remove the center cubby and then the cover below the cubby. The hardest part of this is probably emptying the cubby.:D

Thanks again,

Where you have a cubby I only have a tray which I guess will be easy to remove. I will try that and see where I get to! One way or another I hope to have a fully functioning diff lock by this evening.

A good morning.

To conclude......

Based on advice gratefully received I removed the tray between the seats. I then removed a steel removable plate which gave reasonable access & visibility. I could then see clearly the bottom links of the HI/LO transfer lever as well as the Diff lock linkages. I attempted to move the trasfer box lever and immediately determined how they both should work.

I noticed a short lever on top of the transfer box which should have been operated by the diff lock linkage. Upon moving the lever in the vehicle I noticed the linkages seemed willing to move but the lever on top of the box was rigid. I squirted the top of the box with WD40 and left a few minutes. I then gave the lever in the vehicle a good shove and everything started to move. Success!

All I needed to do now was to ensure everything was well lubricated before re assembly. The lower leverages were easy to squirt with oil but the upper ends of the linkages were more difficult. I managed to attach a small flexible pipe onto an oil can and enlisted wife to operate while I gave instructions from under the vehicle.

Test drive OK. Diff lock engages, light on, diff lock dis engages, light off. Hi & Lo ratio much easier to engage.

Thanks again

Mike

Found your old post today and it worked a treat. I bought an 8 month old 110 from the main dealer - a demonstrator they said but probably just the salesman's company car - the diff lock did not appear ever to have been used and was siezed solid. Having access from top and bottom made freeing and lubricating a straightforward job. Many thanks.
